To all whom it may concern:

Be it known that 1, JAMES A. SUTTON, a citizen of the United States,residing at Packwood, in the county of Jefferson and State of Iowa, haveinvented a new and useful Plow Attachment for Cultivators, of which thefollowing is a specification.

The object of this invention is to provide an attachment for cultivatorssusceptible of use as a surface plow and adapted to be adjusted on avertical axis and also adapted to be adjusted on a horizontal axis.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillustrated by the accompanying drawing, in which Figure 1 is aperspective of a portion of a standard employed in my improvedconstruction. Fig. 2 is a perspective of a stem adapted to be adjustablyattached to the standard shown in Fig. 1. Fig. 3 is a erspective of :1prong adapted to be adj ustably attached to the stem shown in Fig. 9..Fi 4c is a side elevation illustrating the standard, stem and prongassembled and connected at one of several points of attachment, thedotted lines indicating a different adjustment of the prong relative tothe stem. This view also includes a shovel or blade in position forpractical use. Fig. 5 is a perspective of the shovel or blade detachedfrom the other parts. Fig. 6 is a plan of the device shown in Fig. 4,the dotted lines indicating the adjustment of the stem, prong and bladeinto one of several possible positions. Fig. 7 is a side elevation of aconventional form of cultivator showing my improved device attached tothe beam thereof.

In the construction of the device as shown the numeral 10 designates astandard adapted to be secured, preferably in inclined p0sition to thebeam ofa cultivator. The standard 10 is formed with a shank 12 circularin cross-section and projecting from the central portion of its lowerend. The shank 12 is formed with transverse notches or grooves a, Z) and0 arranged in a helical row on the periphery of said shank. The notchesor grooves a, b and 0 are in different horizontal planes and ondifferent lines longitudinally of the periphery of the shank, asillustrated in Fig. 1.

The numeral 13 designates a stem, preferably square in cross-section andconforming in such cross-section to the size and shape of the standard10. The stem 13 is formed with a central bore 14.- opening to its upperend and said bore conforms in diameter to and is adapted to receive theshank 12 of the standard 10. The stem 13 is formed with a plurality oftransverse holes a, b and 0 arranged in a row on the same vertical planeand intersecting the bore 14. The holes a, Z), 0 are spaced apart thesame distances as the notches a, Z), c and are adapted to register withsaid notches respectively at times.

The stem 13 is formed with a tenon 13 centrally of its end opposite tothe bore 14 and a tongue 14 is formed on said tenon and is curvedrearwardly and downwardly therefrom. The stem 13 also is formed withconcave shoulders 18 on opposite sides of the tenon 13. The tenon 13also is formed with a transverse aperture 13 near its forward margin andthe tongue 14 is formed with a transverse aperture 1 1 near its lowerend. The stem 13 is secured to the standard 10 by a bolt (Z insertedthrough one or another of the holes a, b, c, and extending through thecorresponding notch a, 7) or c. When the stem 13 is to be set squarewith the standard 10 the bolt d is passed through the holes a and notcha. When it is desired to set the stem 13 at a small angle to thestandard 10 the bolt (Z is removed from the holes a and is placed in theholes I) and extends through the notch I). When it is desired to set thestem 13 at a greater angle to the standard 10 the bolt cl is removed andplaced in the holes a and extends through the notch c. In eitherposition the bolt d rigidly connects the stem to the standard throughengagement of said bolt intermediate of its ends in a notch of the shank12. A prong 15 is provided and is curved laterally throughout itslength. The prong 15 is bifurcated in its upper portion and is adaptedto receive and embrace the tenon 13 and tongue 14. The upper endportions of the arms of the bifurcated prong are curved to fit theconcave shoulders 18 of the stem and are formed with a transverseaperture 17 registering with the apertue 13 of the tenon 13' and a bolt21 may be mounted in said holes and apertures and pivot-ally connect theprong to the tenon. A plurality of transverse bolt holes 6, e, e areformed in the central portion of the rong 15 and register at times withthe ho e 14 in the tongue 14:. A bolt d may be mounted through one orthe other of the holes 6, e or e and through the hole 14 and adjustablyconnect the prong 15 to the tongue 14. The lower end portion of theprong 15 is formed with a rabbeted seat 19 having a central bolt hole 20and a blade or shovel 16 may be mounted in said seat. The blade orshovel 16 preferably is formed with a bolt hole 20 and may be fixed tothe prong by a bolt 21 in the holes 20, 20. The blade 16 preferably isformed with a beveled margin 16 to produce a cutting edge. To set theblade or plow at an angle to the line of advancement of the cultivatorthe described adjustment of the stem 13 relative to the standard 10 isemployed. To set the blade or plow 16 at an angle relative to thesurface over which it travels the described adjustment of the prong 15relative to the stem, tenon and tongue is employed. In either adjustmentthe blade or plow is used to scrape or out on a horizontal planerelative to the surface of the ground.

I claim as my invention- 1. A plow attachment for cultivators,comprising a standard adapted to be secured to the beam of a cultivatorand formed with a shank circular in cross-section, said shank furtherformed with transverse notches arranged in a helical row on itsperiphery, a stem formed with a bore fitting and adapted to receive saidshank, said stem also formed with transverse holes registering at timeswith the transverse grooves of the shank, a prong pivoted to said stemand articulating on a horizontal axis, means extraneous to the pivot foradjustably connecting said prong and stem, said prong curved between itsends, and a plow fixed to the extremity of said prong.

2. A plow attachment for cultivators, comprising a standard adapted tobe secured to the beam of a cultivator, an integral shank of circularcross-section depending from the standard and provided with a pluralityof helically arranged transverse notches, a stem formed with a boreadapted to receive the said shank, said stem being formed with aplurality of transverse holes adapted to register at times with thenotches of the shank, means co-acting with the said holes and slots forsecuring the stem to the shank,

' a tongue integral with and centrally depending from the stem, a pronghaving one end bifurcated to straddle the said tongue, means eo-actingwith the tongue and the prong for supporting the latter, means forretaining the prong in a fixed position relative to the tongue, and ashovel secured to the extremity of the prong.
